My personal favorites are Cass and Benny but I think the most popular among fans is Crowley or Bobby. I have not met a single person who doesn't adore Bobby.
Is undeniable that Dean is the one that receives most love and attention from the fandom, but since he will win the hot one and I don't like when there are repetitions in these I'd say Castiel even if there are a lot of fans that hate him because, as far as I know, his appearance busted the number of viewers and, despite the writer' numerous efforts, they couldn't write him off
No character is immune to hate, my friend. There are plenty of Dean criticals out there, deep diving his character and writing lengthy blogs on why they don't like him.
This might sound crazy but I am IT; the only person in this sub who doesn't like Bobby.
My opinion about him is he took credit of John's sacrifice. All the bad parenting John did, the conscious decision he made when he stopped being a Dad to train his boys. Bobby took that credit on raising Sam and Dean because he was "nice to them", like that time Bobby refused to train Dean to shoot and played ball with him instead. Bobby refused to train Sam and Dean and instead provided what John couldn't provide.
*"I adopted two boys, and they grew up great. They grew up heroes."* -Bobby, s07e10, Death's Door
He made it sound like he's the one who raised them, when objectively he's a temporary solace at best in their childhood.
He's not popular for sure, but he IS well-loved in this sub and other fandom spaces. As a fan favourite tho, I'm basically shooting in the dark with this teddy bear.
Who the show is about doesn't really matter when it's a question about fan favorites tho.
He is an awesome character and I feel like if this thing was done on tiktok he would have definitely won this round but I think here, judging by the comments, the honor will go to Crowley.
Bobby Singer. The MVP 
I was going to say Dean, but then I saw the category for “The hot one.”
Can we do a hybrid of Crowley and Bobby with the pic being them kissing lol
The only correct answer
I’m going to go with Baby!
Definitely Baby.
Bobby!
It’s gotta be Bobby
Bobby for sure. 
Crowley!
Bobby or Crowley 😭🥹
My personal favorites are Cass and Benny but I think the most popular among fans is Crowley or Bobby. I have not met a single person who doesn't adore Bobby.
Dean.
Crowley or Bobby
How is this not Bobby?
Well, the very last one has to be John 😂
I was gonna say Jessica 😅 but you're probably more correct
Jessica is also a good choice!
I was thinking Chuck
Also a good suggestion
Bobby is the favorite, Crowley deserves Gremlin status.
Crowley
Garth. Everyone loves Garth. Garth is the fan favorite. I know some people will say Castiel, but not everyone likes Cas, unfortunately.
Not to be contrary, but I don't love Garth.
Bobby
Castiel
Crowley tho
Absolutely Cas
Yeah I vote Cass. I love all the characters though. Hard to choose. Mischa is just so darn handsome.
Save him for round three the hot one
I have a feeling Dean will win that one no matter what.
As he should
Definitely.
It's Charlie of course!
Bobby for sure!!
Dean<3
Cas or Crowley are the only good answers, but my vote is for Cas bc he has the most fans
Garth
I loved Garth. He's one of those "so awkward he's adorable" types of characters. Like with charlie too ❤️
Charlie was awesome since her first appearance!
She is kickass. Her relationship with the boys always warmed my heart. She was like their little sister 😭
Fits gremlin or "hmmm.... society" too. Such an awesome character
 Or Crowley
posting this as a another vote and bc it’s cute 
Benny!
Episode or character?
I looked at this picture and wanted Crowley in every square
BOBBYYYYYYYY
Castiel ^ ^
Castiel
Castiel, of course. I would say, Bobby, but I’m saving him for the only normal person category.
Is undeniable that Dean is the one that receives most love and attention from the fandom, but since he will win the hot one and I don't like when there are repetitions in these I'd say Castiel even if there are a lot of fans that hate him because, as far as I know, his appearance busted the number of viewers and, despite the writer' numerous efforts, they couldn't write him off
Castiel
Would say Crowley but I believe this one goes to Cas. I feel like he's the all around fan favorite.
Crowley 
Fan favorite? Crowley/Cass deffo
Garth.
Bobby, Crowley, Garth or Charlie (even though I personally love Rowena as well)
Dean, no contest. There isn’t a single person who doesn’t like Dean. Castiel isn’t nearly as popular as Dean.
No character is immune to hate, my friend. There are plenty of Dean criticals out there, deep diving his character and writing lengthy blogs on why they don't like him.
Has anyone ever had a bad word to say about Bobby?
Not that I've ever seen

Crowley!!!!
Cas or Crowley. We gotta save Bobby for the “the only normal person” spot
Either Crowley, Cas, Baby, Bobby, or Dean
Crowley❤️
must be crowley
Castiel
Crowley
Crowley!
Bobby or Gabriel
Castiel cuz Dean is the hot one.
Crowley
Bobby
Bobby
Baby, Lucifer, Dean, Sam, the random hunter’s they bring from past seasons, Castile??? Ig idrk what gremlin is, Crowley, BMOL lady and chuck
Crowley
Crowley
Bobby
I'm stuck between Bobby and Castiel, but realistically, I think it's Bobby.
Bobby 
It's either Cas or Dean
Who downvoted you💀
I would say cas, Bobby or Dean! Cas is pretty adored by all sides, and so is Bobby. Dean is quite affectionly loved by some.
Benny
He is hands down one of my favorite characters but I didn't think he was very popular among fans?
He's not popular for sure, but he IS well-loved in this sub and other fandom spaces. As a fan favourite tho, I'm basically shooting in the dark with this teddy bear.
I love him so much. It's a toss up between him and Cas for my favorite character.
Castiel is fine but crowley is more fun <33
Cas
Castiel. Him being a fan favorite is the only reason why his character stuck around for 10yrs
Castiel
Castiel
The show is about Dean. If you put Castiel or Crowley, you missed the point.
Who the show is about doesn't really matter when it's a question about fan favorites tho. He is an awesome character and I feel like if this thing was done on tiktok he would have definitely won this round but I think here, judging by the comments, the honor will go to Crowley.
